exciting minority attack on the queenside!

Native English draughts players would rather say "single corner" with reference to squares 5 or 46 and "double corner" with reference to squares 1 or 50. In other countries "left / right flank" or "left / right wing" are preferred.

I will not analyse whole game into details, but I will highlight the most important moments only.
1) 5. 47-42 : inferior move. You should keep draughtsman on 47 on 47 as long as possible. At the opening stage, your primary plan would be to bring draughtsman 46 into game instead.
2) 9. 48-43 : similarly to 5. 47-42, it is inferior move. Even more, you should try to keep draughtsman on square 48 as long as possible, because in the early endgame phase that draughtsman is one which can strengthen your defense or your attack on both sides of the board.
3) 10. 28-22 : typical mistake of beginners; it leads to material loss because of 23-29 shot as it happened in this game. In that kind of position you should eliminate the dominance of black draughtsmen in the centre, therefore, one of plans would be to make exchange 34-30, then 32-27, 37-32, 41-37.
4) 24. 37-32: a rush. By playing 23. .. 24-29 black creates semi-isolated draugtsman which you should try to win by direct attack: 24. 43-38 , followed by 38-33.
5) 27. 37-31: inferior response. 27. 33-28 with intention to gain lost draugthsman back by going into eyes 28-24.
6) 29. 26-21: a critical blunder which, in the right course of game, should lead to loss. You need to pay attention on columns that your opponent is making, and if that column is aimed towards some of your draughtsman, you should eliminate shot ideas.
7) 31. .. 8-13 : terrible blunder which gives some drawing chances to white. Normally, 31. .. 8-12, and white can resign, because white attack is stopped, and white has no good counterplay.
8) 33. .. 16-21: terrible tactical idea, 33. .. 28-23 should be correct approach: it would allow black to keep an advantage.
